Corrosion-inhibiting paints and lacquers

Abstract

This invention relates to corrosion-inhibiting paints and lacquers containing pigments comprising an organic corrosion inhibitor intercalated into an inorganic matrix said pigment having the formula wherein ##EQU1## wherein Me(II)O is at least one divalent metal oxide; Me(III) 2 O 3 is at least one trivalent metal oxide; A is at least one inorganic acid anhydride; I is at least one organic corrosion inhibitor; aq is from 0.5 to 9 moles of water; and x, y and z are whole or fractional numbers and x has a value of from 0 to 1, y has a value of from 0 to 0.7 and z has a value of from greater than 0 to 0.4, with the proviso that the organic corrosion inhibitor is at least 0.5% by weight of inorganic material a process for the production of these pigments and their use in paints, lacquers and lubricants.

What is claimed is: 
     
       1. Corrosion-inhibiting paints and lacquers pigmented with a corrosion-inhibiting pigment having a specific surface according to BET of from 0.1 to 200 m 2  /g, a content of water-soluble components of less than 0.6%, and comprising an organic corrosion inhibitor intercalated into an inorganic matrix having the formula: ##EQU9## wherein Me(II)O is at least one divalent metal oxide; ME(III) 2  O 3  is at least one trivalent metal oxide;   A is at least one inorganic acid anhydride;   I is at least one organic corrosion inhibitor;   aq is from 0.5 to 9 moles of water; and   x, y and z are whole or fractional numbers and   x has a value of from 0 to 1,   y has a value of from 0 to 0.7 and   z has a value of from greater than 0 to 0.4, with the proviso that the organic corrosion inhibitor is at least 0.5% by weight of inorganic material.
